Good To Know

Q: Can these rings be used on a 951 DI model? A: No, these rings are specifically designed for non-DI (direct injection) 951 engines; DI models use different ring profiles and bore dimensions.

Q: Do I need to hone the cylinder before installing new rings? A: Yes, for optimal sealing and ring seating, the cylinder should be lightly honed to the correct crosshatch pattern before installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
